The short version

  • Each has a real cost: AWS API Gateway rEST APIs cost $3.50 per million calls against $1.00 for HTTP APIs, so the older and more featureful type is three and a half times dearer; Postman free plan limited to single user as of March 1, 2026, making it unsuitable for teams without paid plans
  • They diverge on capability: AWS API Gateway covers REST APIs, Postman covers API client.
